A Caseyville man has been charged with concealment of a homicidal death in relation to a murder that happened in August 2011.

The St. Clair County State's Attorney's Office said Dylan Baldwin is accused of hiding evidence in the murder of Melvin Gregory. The evidence is a pair of wooden table legs which Baldwin is accused of throwing in a trash dumpster.

Gregory, 38 of Conyers, Ga., was murdered in August 2011, according to investigators. He had moved to the metro-east about two weeks prior to his death to be with his girlfriend, Donna Mrkacek.

When Gregory and Mrkacek got into an argument on or about Aug. 14, 2011, investigators said Baldwin, Billie J. "Carli" Carson -- both of Caseyville -- and Christopher M. Mays of Pilot Knob, Mo. got involved in a physical altercation.

Madison County Sheriff's Department Lt. T. Mike Dixon, spokesman of the Major Case Squad of Greater St. Louis, said the suspects beat Gregory in a "vicious attack" and then they threw his body in a ditch near Illinois 163, where it was found by horseback riders. The cause of death was determined to be a stab wound to the neck.

Baldwin, Carson and Mays have previously been charged with murder in relation to the case. Mrkacek was previously charged with concealment of a homicidal death.
